  • Publication number: 20050011143
    Abstract: Installed on a top of a structure (1) is a base stand (11) against which damping body (3) movably rests via a linear guide mechanism (12). Mounted between the damping body (3) and the structure (1) or between the damping body (3) and a top of a support housing (14) erected on the structure (1) is a characteristic-frequency adjusting spring or springs (13) with an initial tension being applied vertically. Movement of the damping body (3) causes the spring or springs (13) to be obliquely and longitudinally expanded to apply horizontal component to the damping body (3) upon restoring.

  • Patent number: 6825141
    Abstract: A candidate composition is prepared. For the candidate composition, the basicity was calculated. With reference to the basicity thus calculated, the fusibility with a mold is evaluated. With reference to the result of evaluation, the composition is determined. A glass material is prepared to have the determined composition, melted, and formed. Thus, a mold-press forming glass having the basicity adjusted to be equal to 11 or less is produced.

  • Patent number: 6323977
    Abstract: In an optical transmitting and receiving apparatus. an light transmitting and receiving unit includes a light emitting element, a light transmitting lens, a light receiving lens, and a photosensitive element. The light emitting element outputs light. The light outputted from the light emitting element passes through the light transmitting lens before leaving the light transmitting and receiving unit as outgoing light. The light receiving lens concentrates incoming light on the photosensitive element. A first support member is operative for supporting the light transmitting and receiving unit, and for allowing the light transmitting and receiving unit to rotate about a first axis. A first rotary mechanism connected to the light transmitting and receiving unit and the first support member is operative for rotating the light transmitting and receiving unit about the first axis.
